This sort of approach does not work adequately/reliably for multi-threaded applications. The whole setjmp mechanism is based on restoring a single CPU's stack so it becomes useless when multiple CPUs are involved in the same application. And of course, as you say there can be problems with the C++ exception framework. The best approach requires that the user provide some context (a pointer) to lcms and then lcms invokes the callback, passing the pointer it supplied. This may still require some extra work in a multi-threaded application but it is usable.
